Duplex ultrasonography (DUS) is an essential part of the evaluation of patients with most forms of superficial venous insufficiency. DUS has also become an important tool in directing and assessing the results of a variety of minimally invasive treatments of this disease. In this article, we review the salient aspects of performing an adequate DUS evaluation and the utility of this technique in guiding treatment. KEYWORDS Superficial venous insufficiency - duplex ultrasonography - endovenous thermal ablation - ultrasound-guided sclerotherapy
